(42S) GAUSS LEGENDRE 16 POINT INTEGRATION

[pito]

Hi, I put the listing into .42s (for the 42s Code Editor) and raw format for free42 (see attached).
However it loops forever.
As the function to integrate I used for example:

Code:

LBL "FX"
LN
END

and I stored it to 00 (so RCL 00 returns me "FX").
Not sure that is the way how it should be done, though..
